The authors present the central capacity sharing (CCS) model and derive equations describing its behaviors to explain results from dual-task situations. The predictions of the CCS model are contrasted with those of the central bottleneck model. The CCS model predicts all of the hallmark effects of the psychological refractory period (PRP) pardigm: -1 slope of the PRP effect at short stimulus on...

Stimuli that are clearly positive or negative (hence valence-laden stimuli) have the potential to interrupt unrelated task processing. A typical example is the emotional Stroop effect (ESE) in which responding to a certain task feature (e.g., color) is delayed by the presentation of task-irrelevant valent stimuli (e.g., negative pictures) compared to valence-neutral stimuli. Here we scrutinize ...

Abstract. Given a doubling measure μ on R, it is a classical result of harmonic analysis that Calderón-Zygmund operators which are bounded in L(μ) are also of weak type (1, 1). Recently it has been shown that the same result holds if one substitutes the doubling condition on μ by a mild growth condition on μ. In this paper another proof of this result is given. The proof is very close in spirit...

A change in subtask order in the psychological refractory period (PRP) paradigm increases the effect of stimulus onset asynchrony (SOA) on the second response. We used a paradigm with cued, randomly determined subtask order to test the hypothesis that this SOA by order switch overadditivity reflects order control, via "copying" stimulus order. In Experiments 1a and 1b, overadditivity was eviden...

background: the secular trend in growth is a well-documented and recurrent phenomenon in many developed and developing countries. in this study, we examined the secular trends in birth length and weight among iranian neonates. methods: this cross-sectional population-based survey was conducted between 1991 and 2011. using a two-stage stratified cluster sampling, the birth weights and heights of...

BACKGROUND AND AIM: Giant cell lesions as a group of the oral and maxillofacial lesions are common and potentially destructive. The aim of this study was to assess the frequency of oral lesions containing giant cells in a 22-year period in Isfahan Dental School, Iran.METHODS: In this epidemiological, cross-sectional, retrospective study the archive information in the Department of Oral Patholog...

Climate factors have an impact on plant life cycle, yield, productivity, economy and profitability of agricultural production. There are not a lot studies understanding influence climate variation maize yield in agro-ecological conditions Serbia. The aim this paper is analysis climatic over long-time period, as well assessment the examined parameters two localities Republic For (temperature, pr...

Materials of the discussion about informal philosophical schools held in Alushta (1987–1989, 1991, 1993). The context Ukrainian SSR 1980s and impact Schools on philosophy during period independence are analyzed.

A new investigation of the behaviour of the star 53 Per was performed. New photometric observations allow to confirm twodominant periods p1=2.16 d, p2= 1.67 d.A third one p3= 3.64 d is detected. These long period variations are present in our radial velocities data and in old equivalent width data. The amplitude of the p1 = 2.16 d period increases from 1977 to 1991, while the amplitude of the 1...
